    text
    copied!<p>I have this situation in my model:</p> <p>Product belongs to a Category. TransactionDetail has Product, price and quantity. Transaction has TransactionDetails and date. Shop has Transactions. Group has Shops.</p> <p>They are Doctrine entities and they are properly related. (I don't paste the classes, it would be too long).</p> <p>Thing is I need to query the model to obtain the total products sold (SUM TransactionDetail.quantity) and the total money (SUM TransactionDetail.quantity * TransactionDetail.prize), grouped by Product, From the Transactions of Products of a certain Category in a certain Group that happened in a range of dates.</p> <p>Ok, I did this in plain SQL and it would be something like</p> <pre><code>select TransactionDetail.product, SUM(TransactionDetail.quantity) as quantity, SUM(TransactionDetail.quantity*TransactionDetail.prize) as euros from TransactionDetail left join Transaction on TransactionDetail.transaction = Transaction.id left join Product on TransactionDetail.product = Product.id left join Group on Transaction.shop = Group.shop where Product.category = :paramCategoryId and Group.id = :paramGroupId group by TransactionDetail.product </code></pre> <p>The thing is I have NO IDEA about how do I put this in a DQL query (as plain SQL is not recommended, and I really would like to have a better understanding of the power of DQL).</p> <p>Can you guys help me?</p> <p>Thanks in advance.</p> <p>=============================================================================<br /> EDIT:</p> <p>State of the art query:</p> <pre><code>SELECT d, p, SUM(d.quantity) as quantity, SUM(d.quantity*d.prize) as euros FROM TransactionDetail d LEFT JOIN d.transaction t LEFT JOIN d.product p LEFT JOIN t.shop s LEFT JOIN s.groups g ON s.id MEMBER OF g.shops WHERE p.category = :category AND g.id = :group AND t.date &gt; :from AND t.date &lt; :to GROUP BY p </code></pre> <p>Problems: s.groups is a collection, and so is g.shops. I don't know how in the world this query must be done.</p>
